I don’t know that this study implies that ingesting any of the salts would have an effect on your ability to regulate sleep, but I assume having an ample supply in your system, for your brain to work with wouldn’t hurt.
Now if you have a deficiency, that’s a different story. I’m sure Gatoraide or other electrolyte supplement before bed would be a cheap and safe experiment.
Thanks, the reason I was wondering is because I salt everything, and I do mean everything, yet I sleep very little most of the time. Every now and then I will get 8 hours, but usually it is 3 or 4 hours.
